We're dividing 32299560 by 621 
The aim is to understand the frequency of 621 in 32299560.

On to step 1:
621 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 621

Step 2:
When dividing 32 by 621, we get 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 621

On to step 3:
When dividing 322 by 621, we get 0 with a remainder of 322.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 322 leaves us with 322.
Take the next digit (9) from the dividend and append it to 322, then repeat: 3229 / 621

Moving on to step 4:
621 can be fit into 3229 5 times, resulting in a remainder of 124.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 3105 from 3229 leaves us with 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 621

Let's proceed to step 5:
621 goes into 1249 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 52.0
The remainder is 7 after subtracting 1242 from 1249.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 621

On to step 6:
If we divide 75 by 621, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 520.0
If we take 0 away from 75, we end up with 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 621

Going ahead to step 7:
621 can be fit into 756 1 times, resulting in a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 5201.0
Subtracting 621 from 756 leaves us with 135.
Include the next digit (0) from the dividend after 135, then repeat: 1350 / 621

Advancing to step 8:
The number 621 fits into 1350 2 times, leaving a remainder of 108.
The next digit of our result is 2. 
Result so far: 52012.0
If we take 1242 away from 1350, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
The number 621 fits into 1080 1 times, leaving a remainder of 459.
The next digit of our result is 1. 
Result so far: 52012.1
If we take 621 away from 1080, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 10:
The number 621 fits into 4590 7 times, leaving a remainder of 243.
Use 7 as the next digit of our solution. 
Result so far: 52012.17
If we take 4347 away from 4590, we end up with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 11:
621 can be fit into 2430 3 times, resulting in a remainder of 567.
Put 3 as the next digit of the answer. 
Result so far: 52012.173
If we take 1863 away from 2430, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Let's proceed to step 12:
5670 divided by 621 is 9 with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 52012.1739
Subtracting 5589 from 5670 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
810 divided by 621 is 1 with a remainder of 189.
The next digit of our result is 1. 
Result so far: 52012.17391
If we take 621 away from 810, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 14:
When dividing 1890 by 621, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 52012.173913
If we take 1863 away from 1890, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 15:
If we divide 270 by 621, we get 0 and a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 52012.173913
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 16:
The number 621 fits into 2700 4 times, leaving a remainder of 216.
The next digit of our result is 4. 
Result so far: 52012.17391304
If we take 2484 away from 2700, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 52012.17391304 and a remainder of 2.16e-07.
